This novel low-cost, low-power learn-to-solder kit was designed by a CWRU student for think[box]. The device measures the electric signals generated by human muscles and displays them on an LED bar graph. It is intended to be used for learn-to-solder workshops, and as a human-machine interface for other student's projects. Bird Technologies of Solon, OH contributed to and manufactured the final product. Several prototypes were made with think[box]'s PCB router.
